Radiographic cephalometry is a biomorphological measuring method used
in the prosthodontics as well, and for the facial profile analysis of
persons with complete dentures. The purpose of this examination was to
objective the facial esthetics in, patients with complete dentures. T
he measurements were taken from LL X-ray radiographs obtained by the a
pparatus ''Ortoceph 10'' (Siemens, Bensheim, Germany). On the sample o
f 80 subjects a convexity angle of facial bone structures (N-A:A-Pg) a
nd: profile angle of soft facial tissue (ft-unt : int-ct) have been ex
amined. The subjects were divided into a group with upper and lower co
mplete dentures (20 males and 20 females) and a group with natural tee
th of eugnatic characteristics (20 male and 20 female). The measuremen
ts were taken by standard protractor at 0.5% precision. The statistica
l analysis within and among groups has been made by F-test and t-test
respectively. The results showed that the bone structure convexity ang
le span a range between 0 degrees and 5.5 degrees (X=2.5 degrees), and
the facial profile angle between. 139.5 degrees and 155 degrees (X =
149 degrees) in persons with complete dentures. In persons with natura
l teeth the values of bone structure convexity angles span a range bet
ween -0.5 degrees and 4.8 degrees (X = 2 degrees), (and the facial pro
file angle between 136 degrees and 155.5 degrees (X = 151 degrees). Th
e results of tests proved that there were no statistically significant
differences in. examined variables between persons with natural teeth
and those with complete dentures (p > 0.05). The conclusion is that c
linical! methods of determining the vertical and horizontal intermaxil
liary relations used in the designing procedures of complete dentures
were reliable enough in reconstruction of examined angles of soft and
hard facial profile structures.
